Gustav I ran into the same issue.
My approach was to use the keepExternalReferences option to stop the external references being included explicitly. I then produced a small post processing application that read the converted file keeping track of all the proxy nodes and then replacing duplicate instances with references to a single instance of the proxy node. This significantly reduced the memory usage and speeded up loading.

I do not have any problem when loading the OpenFlight file directly, but I get a problem after converting the file to the .osg format with osgconv. When I load the .osg file with osgviewer the memory consumption increases more and more until 2GB is used and the program crashes. When I load the original OpenFlight file, the osgviewer only uses about 30MB of memory. I believe that the problem has something to do with external file references that are inside ProxyNode:s in the converted .osg file. I have a tree model that is placed at lots of positions. Thank you!
